Determines if this geometry, transformed by the given transform
, will completely cover all surface area of the given rect
.
This is a conservative estimate useful for certain optimizations.
true
if the transformed geometry is guaranteed to cover the given rect
. May return false
in many undetected cases where the transformed geometry does in fact cover the rect
. Reimplemented from impeller::Geometry.
